Can be small, can be large, are made of biomes, have nonliving parts.
Agata [3.3K]3 years ago
5 0

Answer:

all of them apply

Explanation:

In my opinion all of them apply (except the 4th one). Ecosystems can be small, big, have living and non-living parts and they are made of biomes. Not only can ecosystems vary in size, but they can also differ in just about every imaginable biotic or abiotic feature.

kondor19780726 [428]

Answer:

C. able to relieve hemophilia symptoms.

Explanation:

Hemophilia is a genetic disorder. It is an X-chromosome linked recessive disorder. It is caused by deficiency of functional blood clotting factor VIII. The Functional factor VIII al deficiency may be inherited or arise from spontaneous mutation.

The symptoms of hemophilia can be reduced partially by functional Factor VIII. This will help to counter functional deficiencies in factor VIII in the haemophilic individuals.

Match the cell organelle to the organ or organ system in your body that does the same job.

<span>Nervous System - Nucleus - control (responding to certain neurotransmitters by allowing transcription factors to be formed) Respiratory System - Plasma Membrane (alveoli allow certain particles into the cells but want to keep contaminants out) Reproductive System - Nucleus - DNA (determines in part the genome and developmental process of the offspring) Digestive System - Mitochondria (want full redox reaction to occur in the organelle based on nutrients extracted from food) Integumentary System - Cytoskeleton (for support as well as in the construction of the basal lamina) Musculoskeletal System - Endomembrane System (think about the sarcoplasmic reticulum and the effect of increased surface area when calcium is released) Circulatory System - Passive Transport (through capillaries especially)</span>

Genetic dominant means and why it makes a difference in crossbreeding animal
Dovator [93]
Genetically dominant means that the trait will always be dominant to the genetically recessive trait as long as the allele for that trait is present. 

Let's say you have an R allele that codes for a brown coat and an r allele that codes for a white coat. Say the R allele is genetically dominant to the r allele. 

If you have an animal with the genotype RR or Rr, it will show a brown coat because the genetically dominant R allele is present.

Only if the animal as a rr genotype will the white coat show because the genetically dominant R allele isn't present.

When you crossbreed, genetic dominance can be important because it can increase the chances you'll have more diverse offspring with increased chance of survival since the dominant traits, if favorable, will always show for a trait.

1. In , a population isolated by a geographic barrier becomes a new species as it accumulates changes by natural selection or ge
Zielflug [23.3K]

Answer and Explanation:

  1. allopatric speciation: occurs when a population becomes isolated by a geographic barrier, becomes a new species as it accumulates changes by natural selection or genetic drift. Also known as <em>geographic speciation.</em>
  2. sympatric speciation: a new species that may arise as mating and gene flow are reduced between populations that share the same area. In other words, a group of people from the same ancestral population that may evolve differently until they no longer interbreed and develop into a entirely different species.
  3. polypoid speciation: mostly commonly occurs in plants, where an accident in cell division results in extra set of chromosomes. This has been a major source of speciation in the angiosperms. Polypoidity increases biodiversity and a it is a source of new genetic material for evolution.
  4. Both allopatric speciation and sympatric speciation depends on the establishment of reproductive barriers, which prevents gene flow between a new species and its parent species. Reproductive barriers may arise due to geographical, behavorial, psychological or genetic differences which may prevent species to breed successfully with related species.
  5. Adaptive radiation: occurs when a species gives rise to many new species after colonizing a region with diverse habitats. It is a rapid increase in a number of species from a single common ancestor.
